Architectural Overview
This table assumes that the control flag MSEL is set.
2.3.1
EMI REDUCTION
This table assumes that the control flag MSEL is set.
The COP8CBR/CCR/CDR devices incorporate circuitry that guards against electromagnetic interference -
an increasing problem in today's microcontroller board designs. TI's patented EMI reduction technology
offers low EMI clock circuitry, gradual turn-on output drivers (GTOs) and internal Icc smoothing filters, to
help circumvent many of the EMI issues influencing embedded control designs. TI has achieved 15 dB–20
dB reduction in EMI transmissions when designs have incorporated its patented EMI reducing circuitry.
2.3.2
IN-SYSTEM PROGRAMMING AND VIRTUAL EEPROM
The
device
includes
a
program
in
a
boot
ROM
that
provides
the
capability,
through
the
MICROWIRE/PLUS serial interface, to erase, program and read the contents of the Flash memory.
Additional routines are included in the boot ROM, which can be called by the user program, to enable the
user to customize in system software update capability if MICROWIRE/PLUS is not desired.
